A focus group is a group of people assembled to discuss and provide feedback on a particular topic. Focus groups are useful for gathering attitudes, feelings, beliefs and reactions from respondents in a way that individual interviews or surveys cannot. They allow for a multiplicity of views to be shared and for more information to be obtained in a shorter period of time compared to other methods. Focus groups are particularly helpful when power differences exist between participants and decision-makers, or when exploring the language and culture of particular groups. While focus groups can help generate hypotheses and develop survey questions, the findings cannot be generalized to the whole population due to the small number of participants.
